Physical existence, ie what physics is analysing, is that which is potentially knowable to us. We will never know a lot of it, but it is the potentiality which delineates it. And it is knowable because it is physically receivable (or can be validly hypothesised as being so, ie virtual sensing). There may be an alternative to what is potentially knowable to us, but since we cannot know it, that is irrelevant (this is science, not religion). We cannot transcend our own existence. The subsequent processing of what is physically received is irrelevant to the physical circumstance, as that has already occurred, that processing results in a perception of what was received.

Physical existence is purely spatial, there is no time in any given existent reality, that is concerned with the rate at which reality alters, and there is only one reality at a time (a physically existent state of whatever comprises it), in a sequence (ie the present).

    Zoran,

    A simple question about time;

    Does the earth travel this fourth dimension from yesterday to tomorrow?

    Or does tomorrow become yesterday because the earth rotates relative to the sun?

    Is time the basis for action, or an effect of it?

      Hello John.

      First of all, thank you for reading my essay, for your comments and advice, I thought you might like parts of it. But, I can't believe how quickly you got the gist of it. I was in the process of adding a short comment to your essay, but I now intend to change the gist of it so that you can understand both works from a slightly different perspective. But it's quite long, so I hope you don't mind.

      Many thanks.

      Zoran.

      Hello Mr. Fisher.

      Thank you for reading my essay. I will try to post a comment on you essay, if I can, but I am sure you appreciate that most essays here are beyond my technical expertise, and I should not comment on something I don't understand. That said, I point you to the comment I left for Mr. Maguire (Essay 1787), which I think you may be interested in.

      Zoran.

      Hello Mr. Merryman.

      Thank you for reading my essay. Unfortunately I can't even try to answer your question because I do not understand it. I suggest you have another look at my essay, within which I specifically exclude the possibility of the fourth dimension. And I am sure you can appreciate that commenting on something that does not exist should be left to that exact statement, that is, that it does not exist. I hope that helps.

      Zoran.

      Hello Paul.

      Thank you for reading my essay, and your relevant comments. I must say, I agree with many of your comments, but I disagree with some also. For instance, I do not believe we should lay down and turn over at every dead end, and I am glad to see essays here urging us on, and others saying give it a chance; this is science, and both sides play a part. You are correct in saying that we are always one step behind what is actually happening, but with logic and real science we can make predictions and in that sense be one step ahead. In my essay I speak of the block-universe conjured up by Presentists in order to accommodate Einstein's fourth dimension, something which demands an external observer, and something which looks more like theology than science to me. I suggest we all stick to science.

      Zoran.

      Zoran,

      That's my point as well. There is no 4th dimension. It is a model of sequence, like narrative. Which is ironic, because physics insists their models see beyond basic intuitive beliefs, yet time as sequence is as much an effect as the sun moving across the sky. We experience time as sequence, much as we experience the sun moving, but it is the earth and the events which are moving the other way.

      Zoran,

      Hi. Nice essay! I'm not very well versed in Kant's philosophy, so a lot of your essay was over my head, but a couple of things really stood out that I agree with. I thought we'd have some agreements based on your comments at my essay. Anyways, my two comments are:

      1. If I understood it correctly, you point out how all things, material and supposedly immaterial spring from a metaphysical fabric. I totally agree and would say this metaphysical fabric would be similar to what I called an "existent state" in my essay. The following quotes from your essay were very good!

      "...we do not shy away from the certainty that all things truly immaterial, i.e. happenings, spring from material, cell and fabric. ...Nonetheless, in the following pages we present for judgement a hierarchy of "fabrics à priori" from which all things spring, even the subatomic phenomena described by the standard model of physics...."

      "When it comes to things immaterial or without extension the word abstract has a place, but, apart from gravity and some loose threads in the standard model of physics, metaphysics is now concrete, and with cognitive mechanics the ethereal meaning of the word will be relegated to the side line, and the flights of fancy of mathematics also."

      2. In your section on Separation, Aggregation and the Void, you suggest, I think, that the void performs two seemingly opposite functions and may be the basis from which the Cosmos springs? With this, I totally agree and have argued at my website and in a previous FQXi essay that the words "something" and "nothing" are two different names for the same underlying thing, the supposed complete lack-of-all. I argue that if we got rid of everything we could think of from our universe (all space, time, matter, volume, energy, matter, ideas/concepts, and minds), than what's left really isn't the lack of all existent states. Instead, the complete lack-of-all, in and of itself, defines the entirety of what is present, and as such is an existent state (similar to the null set). That is, our word "nothing" for this supposed lack-of-all is incorrect. We can never really have "nothin" because even the lack-of-all is an existent state. So, if we could think of the lack-of-all, or the void, in a slightly different way, we'd see that it's an existent state, or "something", and can be the existent state from which everything springs.

      I'm not sure if you were getting at something similar, but it sounded a little bit along the same lines.

      Well, it was a very good essay, and I agree with your main points.

        Sir,

        I apologies; my first answer was based on a quick search of essays for yours. I fail to see how I missed it, and your valued insights. I would like to add something to my previous answer, I hope you don't mind. While I say that the fourth dimension (time) does not exist in actuality, there is no doubt in my mind that our insights can not exist as knowledge without the representation of time as a fourth dimension in some way; and that's the trick, to know the trick. This trick, is different to the trick which makes a simultaneity of impressions on our intuitive canvas possible, but it's a trick nonetheless, and as evolving creatures we have learned a great many tricks which we must now separate from reality.

        Thank you for your post and your essay.

        Zoran.

        Hi Roger,

        Thanks for reading my essay, I enjoyed your essay because you're trying to get to grips with the nature of our existence. And while I can't say that something and nothing are the same thing, there are a great many things we agree on. I try to think of the void as a backdrop, and when I think of the Cosmos as a thinking thing, the backdrop is the lack of thought, and it doesn't matter whether I zoom out to imagine whatever I can imagine, or zoom in until my imagination can't imagine anything smaller, only to find room for more of those smallest things, I find it easier to imagine the space between those smallest things as a lack of thought, because if I think of it as room for more things I think of it as something. At some time in the future we may find that a lack of thought is something, but not today.

        Hello Hoang cao Hai,

        Thanks for reading my eassy, and your best wishes.

        Zoran.

        Mr. Mijatovic,

        I am a decrepit old realist. I write like one. If you understand the story of Little Red Riding Hood, you will understand my essay.

        Zoran,

        Thank you for appreciating this. You would be surprised how few people with any background in physics are willing to consider it. It seems so simple and obvious when you stop to think about it, though given that sequence is the basis of history and logic, it is a bit "counterintuitive," but presumably physicists are able to think counterintuitively. The real problem is that it upsets the "fabric of spacetime" as a causal property. Not only does this eliminate the conceptual basis for such ideas as wormholes and blocktime, not to mention gravity as curvature of this "fabric," but an expanding universe as well.

        Arelated issue I keep raising about current cosmology is that while it assumes space expands, it maintains a constant speed of light against which to judge it. For example, if two galaxies are x lightyears apart and grow to 2x lightyears apart, that is not expanding space, as measured in lightyears, but increased distance. Consider Einstein said, "Space is what you measure with a ruler." If the ruler of lightyears is not expanding, but more are being used, that is therefore not expanding space! I recently debated this point over at Jennifer Ouellette's blog at SciAm, with Cormac O'Raifeartaigh, if you want an example of how it just doesn't register, even if it isn't refuted.

        Ps, I'm brodix. Debate starts at post 15.

        I understand, and I hope my comment on your essay helps to stub the toe of all those who are not looking where they're going.

        Cheers.

        John,

        Thanks for the link to Jennifer's Blog; her picture at the bottom looks better than the one at the top, but then it may have been a mind boggling hair day when taken. She sounds down to earth, and anyone who knows how to drink a pint can tell time in hierarchical space-time. Sorry, couldn't help myself; anyway, my work is obscure, me too, but if she tries to take strips off me I will protect myself. Beware! I protect myself with words, I do not throw symbols, idols, or a bunch of heavy books at those who throw shoes. But I am sure I will eventually be caught out in my spelling, because it's attrowscious.

        Zoran.

        Zoran,

        I, of necessity, tend not to take myself too seriously, but as you say, am willing to defend what I see as important.

        John,

        I am sorry, when I used your link and found that Jennifer, in her sun glasses, sipping on a bowl full of Margaritas, looks like my x, I thought for a moment I was being had. I will now try to answer you question as best I can.

        There was a time in philosophy when everything was an idea, that is, if you couldn't explain what an idea was in five thousand words or less, by using the word "idea" as every second word, or if you couldn't add one idea to another to make five, not only could you not add up, you had no idea what you were talking about. Descartes used the word "idea" with precision, and his conclusions and insights are not a dead end, they are a drop of honey to put in your tea, from time to time, to make the moment a little more that it would otherwise be. Kant gave us four flavorsome cubes, intuition, conception, à priori and à posteriori, which are a treat for any cook trying to cook up a philosophical cake. I love cooking with centripetal, centrifugal, secret and open conscious modes, and moments within moments, and as you say, the sequences of moments which are the sequence of events which make experience what it is. I love differentiating between the memory we call intuition and the memory we call conception, because in the end everything is just memory and a sequence of memories. And with all these ingredients you too can cook up the answer to everything for yourself, literally. But, you must trust your ingredients, and trust takes time to build. Metaphysical space-time was cooked up with all these ingredients, and I think it tastes great, but I suspect it has taken the critics by surprise, because I haven't heard a peep out of them.

        Zoran.

        Hello, Zoran!

        I read your essay pleasures. It is good that you exacerbated concept of "space", Kant's ideas and consider how the unity of the scientific and philosophical knowledge and traditional knowledge. The problem of the structure of space in physics, its dimension, I think has arisen because absence of thorough "General theory of action" and, as a result, the ontological groundlessness of the whole system of knowledge. The key here may be the idea of Kant's concept-figure synthesis, the concept of "state" (of matter), the doctrine of the "form" and the ancient idea: "As above, so below." We also need a modern interpretation of the traditional knowledge of the whole system into account the achievements of science. I only have one question. What is more logical reasoning and in line with our intuition, experience and thousands of years of tradition: "In the Beginning was the Logos ..." or "In the Beginning was the Big Bang?" Appreciation and wishes for success! Regards, Vladimir

          Hello Vladimir,

          Thank you for reading my essay, and more especially your question. Our biggest problem in science has always been the context within which our answers must exist, and it is always this context which makes our answers unintelligible. I believe my essay is the context within which scientific questions can be answered intelligibly, and that encourages questions, and I love that. If I ask what conservation of energy is, within hierarchical space-time, I get an intelligible answer which sees the loss of entropy in one domain conserved in another, awaiting recirculation. If I ask what conservation of creation is, I get the most beautiful answer, but the fly in the ointment is singularly, it destroys the symmetry of what I see everywhere. This context allows all of us to understand the Heisenberg uncertainty principle in terms Darwin would understand, in evolutionary terms. It answers the question of why some things do not know where they are, or where they're going until they get there, that is to say, they can be in two places at the same time. Things in intuitive space-time can not know where they are and where they are going at the same time, but in conceptual space-time they can know both at the same time. When you see evolution as the means to knowing where we are and where we are going at the same time, you can't help but love it. I love the context which allows me to talk science in a way that everyone can understand.

          Zoran.
